INVEN'I'OR e thereon will enga e ehe s IGSLI' side of ohe motion of the knuckle-tail, Fig. 6.

- formin locking projecuion 13 on alle couplehead,

so that the slm;ft can only be retracted in one single position of its rooation. When the arts of the coupler have been assembled thelever 9 prevents the shalt from getting into saicl osition. The outer prmecting e1rd of the shaft preferably has a crank 14, enabling it t be rotate d by a suitable operatirw-rod. The lever 9 has a head 9, which is aalpted' to engage the shoe d at the foot of theopening member of' the locking and opening piece; If when the parts are in ehe locked osition shown in Figs. 2 anal 3 the 0pemtor desires to unlock the coupler he turns the crank-shaft by rhearis 0f the operah1gr0d thus 1aisillg the lever 9 int0 enga gement with th e shoe d of the locking and pening pisse. The-locking and opening pieoe firso moves forwardly and disengages the shoulder f from the under side 0f the knuckle-tail, and then it is lifted by the le'ver 9 along the gui(lin-surf0 8, as illus trated in F1g 5, until the lockin head passes above the level of the knuck e, :md is thus f1eed from' locking engagemehb there- With. If it is desired 'llQ leave the arts in lock-set position the operato'r releases alle operating-shaft 1G, whereupon the locking and opening piece "drops sli htly l1oulder 4 011 13l16 *nuckle-tail within ehe hooked portion thereof, tl1us supporting thf: locking and 0 ening piece in lock-set posi tio'n, with its ead still above the plane of By reason cf the construction of these parts the lock-senting willbe effected even thou h the knuckha may have been moved slightfy f01 Ward, as the tendenoy 0f the lever 9 is 130 move the looking and opening p'i6ce into 0011- tact with ehe rear side of the knuckle. By the shoulder 4 on ehe real side in stead 0 on the t0p ol? the k'nuckle and locating it within die hooked portion of the knuckle the locksetting can be accomplished b a shorter motion of the lever and the coupler-h'ead can the1efore b0 made of lass height. This construction aifords the furth'er adva'ntage that the lock will remain inloqk-seb posltion during a large am of motion of the knuckle. If I1OW ehe cm 120 which the kmickle is applied be separated anal the lip frorn the companion car With Wh'ich ibis 0011 led ehe knuckle Will swing fre'aely open wit ouu any further manipulation on the' part of the brakeman, and as it n1oves-open it Will eventually. disengage tl1e shoulde1 .4. fron1 the lip e, ancl *the locking and opening piece 6 will drop down'until t11e locking-head o1 vEhe lock rests upon. the tail of the knuckle, .in which position Lt Will remain until the knuckle is again moved back inpo closed position, when the lock will fall int'o locking position. When it drops t0 loeking position, tl1e upper member g ofthe piece 6 Will engage 9,11 inclined guiding surface, h 011 l3l16 knuckle and Will be directed thereby ba.ckwardly, so as t0 bring the shoulderfdnto' its confined position beneath the knuokle. If it is desired to trip the lock-set Withou-t firSt separating the car to Wh;ih th knuokla is applied from ehe ad-jaoent car, this cm1 be done by means of a pin wh-ich is inse-rted th1ough a, hole in the wall of tbe coupler, as shown in Figs, 1 and 2, thepositionof the hole being such that ehe pin willengage ahe lockingand opening iece, willlift it slightly so*as to free it from t 1e lip 01 shoulder 4-, und

cause it to d1 opback inoo its locking positi0n. If it is desiredto move tl1e -locking and openi ng piece bey'ond tlie loek-set posi tiouinto the open position, and thus top0sitlvely move {ehe knuckle open, the-motiot1ol the lever 9 is oontinued beyond thaii which is shown by dotted lines in Fig. 6i and there-l upon engaging =the shoe d it Will pu shv the openin member of -the-. iiece 6 -fc rwafdly und wi l push thejknklefully=open.- During this motion the groove 6 av the top of -the locki1'1 and 'opening piece by engagement w.th t e -rib 7 atthe roof ofthe coupler-head Will prevent said piece from= biecoming'dis' placedout of proper position. This is the only functionoi the -rib 7 since tl1e work 0f opening is done by the pushing zangagement 0f uhe lever 9 with the lower end of the opening member of the -locking and opening piece,

and, broadly speaking, my invention is' not 1 10 limited t0 the employment of zmy such ribl The opening 0f the knuokle is efl'ectedby the leverage 0f the lever 9, which i-s of sonsiclerable l ngth and therefore the efliciency of tl1e d.evitzeis not impaired by the fach that '1 15 the locking and opening piece engages the knuckle near its pivot-pin. The advuntage of thus engaging the knuckle near its ivot is tha1 21 very wide opening of ul1dknucgle, can

be obtained with a, relatively short swingof 'lhis adds the logzkingand opening piece. gratly to ehe .racticul usefulness 0f the de vice. As the lock, but is inclepend-ent thereof, the parts Will not bind and ar e not a t to be put ou't 0f 0rder. When the knuck ehas been thrown to it-s fully-open position, the operatopreleases ehe opening mechanism, whereupon t-he lever ever is not attached to the the finger 17 beneath tl1e lock.

the lever 16, Which 9 Will drop back to its original po sitioii (shown in 1*igs. 1, 2, 3 the locking anti. operv ing pi ace 6 Will drop, and its locking-head Will rast upon. the knuckle ancl Will remain there until the knuokle is again closed, when it Will fall into l0cked posit1on, as above explained.

In the.drawings 011 Sheet 4 thereof, 1 Show a locktripping device 0f modified construction, wnicn I may use in plane of the pin 15 of Fig. 2. This device consists of a lever 16, journaled' in a recess in the couplerhead and provided With a finger 17 and an upwardlyprojecting horn 18. "When the lock is moved 1nto lock-set position, the horn 18 is engaged by the lock and moves the 1in e1 '17 underneath t-he head g ol the lock. 50 long as the lock is in lock-set position the tripping device is in position to litt the lock up from the shoulder 4, by reason of the engagement 0f T0 trip the lock, the Operator depresses the unter end of projects outside the couplier-head.
